MALCOMIB M. CURRIE, OF HOUSTON, TEXAS.

CUTTER.

Specification of Letters Patent.

Application filed March 28, 1912.

Patented July 16, 1912.

Serial No. 686,794.

To all whom it may concern:

Be it known that I, MALOOMB M. Cuinnn, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Gutters, of which the following is a specification.

My invention relates to new and useful improvements in cutters.

The object of the invention is to provide a cutter of the character described having a plurality of adjustable cutting blades, which may be readily secured therein and removed therefrom and which also may be easily adjusted in the supporting disks.

With the above and other objects in view, the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of the cutter, showing the cutting blades in the position in the supporting disks which they will occupy before said disks are drawn together. Fig. 2 is an end view thereof, showing the blades in dotted lines. Fig. 3 is a side elevation of the cutter, showing the disks drawn together and the cutting blades in the position they will occupy when the cutter is in use. Fig. 4 is a sectional side elevation of the cutter, and Fig. 5 is a diagrammatic fragmentary view of the cutter mounted upon a suitable frame work an showing the cutter casing opened. 4

Referring now more particularly to the drawings, wherein like numerals of referencedesignate similar parts in each of the figures, the numeral 1 refers to the cutter shaft which carries the rigidly mounted circular disk 2. Opposing this disk and slidably mounted upon the shaft 1, is a similar disk 3. This disk 8 is keyed to the shaft 1 so as to rotate therewith and is adjustably secured upon a threaded portion of the shaft by means of the nut 4. The inner face of the disk 2 is provided with two opposing arcuate grooves 5 and 6, said grooves being arranged at an equal distance from the center of the disk on opposite sides of its inner face and being arcs of greater circle than the disk carrying the same. The outer sides of these grooves are abrupt forming shoulders 7 and 8, while the inner sides thereof are sloping, while along the angle formed by said sides, extend deep narrow grooves 9 and 10. The inner face of the disk 3 is provided with similar grooves, which respectively oppose the grooves 5 and (3 and which are numbered 11 and 12, respectively, said grooves 11 and 12 being similar in all respect to their opposing grooves 5 and 6.

The cutter is provided with two cutting blades 13 and 14. These blades are thin, flexible plates of some suitable material, such as steel and are substantially square in shape and have all four of their edges sharp so as to form cutting edges. 'lVhen it is desired to place the blades in the cutter, the nut 4: is unscrewed and the disks 2 and 3 are moved apart and the cutting blades are then placed between the disks, assuming the position shown in Fig. 2. The nut 1 is then screwed up against the disk 3 and the disks are brought closer together and the cutting blades are gradually forced to assume an arcuate position, as shown in Figs. 3 and 4. by reason of the sloping sides of the grooves 5, 6, 11 and 12, until the sharp edges thereof are forced into the narrow grooves 9 and 10 of the disk 2 and their corresponding grooves of the disk 3, which said grooves are narrower than the thickness of the cutting blades and the sharp edges of the cutting blades are wedged in said narrow grooves and the cutting blades are thus held firmly against the abrupt shoulders of the grooves 5, 6, 11 and 12 and the cutting blades thus secured firmly in place.

It is readily apparent that the cutting blades may be adjusted in their grooves in the direction of either of the opposite sides of the periphery of the disk so that either free edge may be made to project beyond the plane of the peripheries of the disks 2 and 3 and thus forming a cutting edge and by a proper adjustment of the cutting blades the cutter may be made to operate either forward or backward.

The shaft 1 is mounted in suitable bear-- ings 15, carried by a support 16. The shaft is provided with a suitable drive pulley 17 which receives rotation from the drive belt in operative connection with a motor, (not shown). The cutter operates in a suitable casing 18 which in Fig. 5 is shown withdrawn, so as to expose the cutter to view.

This device is specially designed to be used in cutting ears of corn and other feed for use as stock food and the feed to be cut is fed to the cutter through a suitable feed inlet 19.

While I have shown only one form of my cutter, I do not desire to limit myself to. the specific form shown, but hereby reserve the right to vary the construction thereof so long as I do not depart from the scope of the appended claims.

hat I claim is 1. A device of the character described, in-

cluding a suitable shaft and two opposing disks mounted thereon, one of said disks being rigid with the shaft and the other being slidably mounted thereon, but keyed thereto, each disk havingan arcuate groove in the inner face thereof, said grooves being similarly shaped and correspondingly located, a cutting blade composed of thin flexible material arranged between said disks whose opposite edges fit into said grooves.

2. A device of the character described, consisting of a suitable shaft and two circular disks mounted thereon, one of said disks being rigid with the shaft and the other being slidably mounted thereon, but keyed thereto, the inner face of each disk being provided with two oppositely disposed arcuate grooves, the grooves of one disk corresponding in shape to the grooves in the other disk, and a plurality of blades carried between the disks, the ends of each blade fitting into the corresponding grooves of the disks.

3. A device of the character described, consisting of a suit-able shaft and two opposing disks mounted thereon, one of said disks being rigid with the shaft and the other being slidably mounted thereon, and keyed thereto, each of said disks having an arcuate groove in the inner face thereof, said grooves being eccentric with reference to the disk and similarly shaped and correspondingly located, a cutting blade arranged between said disks whose opposite ends fit into said grooves, and means for holding said slidable disk firmly against said blade.

4. A device of the character described, consisting of a suitable shaft and two oppos ing disks mounted thereon, one of said disks being rigid with the shaft and the other i being slidably mounted thereon, and keyed thereto, each of said disks having an arcuate groove in the face thereof, said grooves being eccentric with reference to the disk and similarly shaped and correspondingly located, the outer side of each groove being abrupt and the inner side being sloping, a cutting blade arranged between said disks whose opposite ends fit into said grooves, and means for holding said slidable disk firmly against said blades.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
